Jordyn Chace is a huge fan of classic murder mysteries. As a geneticist and wildlife biologist, she considers herself an investigator.

But instead of solving human crimes, she uncovers clues that may help contribute to the recovery of a once-common North American mammal: the little brown bat, Myotis lucifugus, a species now on the brink of extinction.

Invasive silver carp have been spreading throughout the Mississippi River Basin since their introduction a half-century ago. Yet, try as they might, the fish have not advanced beyond a particular stretch of the Illinois River north of Kankakee.

Changing precipitation patterns in the Neotropics, one of Earth’s most biodiverse regions, could threaten two-thirds of the area’s bird species by the year 2100 if climate change goes unchecked, according to new research led by the University of Illinois Urbana-Champaign and

Elephant conservation is a major priority in southern Africa, but habitat loss and urbanization mean the far-ranging pachyderms are increasingly restricted to protected areas like game reserves. The risk? Contained populations could become genetically isolated over time, making elephants more vulnerable to disease and environmental change. 

Domesticated animals play a prominent role in our society, with two-thirds of American families enjoying the companionship of pets and many others relying on animal products for their nutritional needs. But the process of domestication remains a bit of a mystery. Convincing wild animals they are safe enough to coexist and mate in enclosures and in close proximity to humans and other animals is no small feat.

Following decades of decline, even fewer birds will darken North American skies by the end of the century, according to a new analysis by scientists at the University of Illinois Urbana-Champaign.

Among the snowbirds returning north for the summer, A24 is special. For one thing, A24 is an actual bird: a Black-crowned night heron, to be exact. And it has just returned to Chicago to join hundreds of its kind nesting near Lake Michigan. But unlike the human snowbirds that share A24’s migratory habits, this bird is helping to inform conservation efforts in the city and far beyond. 

Today, the Walder Foundation of Chicago announced the recipients of its 2024 Biota Awards, recognizing early-career researchers working to understand, protect, and restore the unique and diverse ecosystems in Chicago and around the world.

Researchers from the Department of Natural Resources and Environmental Sciences tracked bird diversity in public parks and private backyards in twin cities in Illinois with significantly different development histories and green space management practices. They found that birds rely on both public and private spaces in different seasons and for different reasons. The study linked park management practices aimed at conservation and restoration to increased bird diversity and the persistence of rarer species.
